du Bus de Gisignies, 1855,
“Senegal”; error = Ghana.
Until recently considered conspecific with C. gularis, and clearly very closely related, but differs from all races of latter except benguellensis by its plain vs vaguely streaked back (1); plain (or barely marked) dirty white vs dark-mottled chin (2); weaker white throat (1); browner (less blackish) head markings (ns); slightly paler mid-belly (ns); smaller bill and shorter tail (effect size for tail –3.65, score 2); but longer wing (effect size 1.36, score 1); it differs from C. g. benguellensis by its plain dirty white vs dark-mottled chin (2); weaker white throat (ns); streaked vs almost plain brown head (2); paler brown upper- and underparts (1); slightly smaller bill and notably shorter tail (on tiny sample; allow 2). Further, race elgonensis from South Sudan and W Kenya does not respond to playback of song of nominate C. gularis. Proposed race uamensis (described from Basum, near R Ouham, in S Chad) treated as a synonym of elgonensis. Emendation of name montanorum to montium in HBW was unjustified. Three subspecies recognized.
